Cluster Environment Requirements
If you have a cluster environment, you must complete the following steps in addition to setting
environment variables discussed in “Setting Environment Variables” (page 48):
1. If you plan to place the root disk group under the control of VxVM, decide into which disk
group you want to configure it for each node in the cluster. The root disk group, usually
aliased as bootdg, contains volumes that are used to start the system. VxVM sets bootdg
to the appropriate disk group if it takes control of the root disk. Alternatively, bootdg is
set to nodg. To check the name of the disk group, enter the command:
# vxdg bootdg
2. Decide on the layout of shared disk groups (as one or more shared disk groups may exist)
and determine how many you wish to use.
3. If you plan to use the Dirty Region Logging (DRL) feature with VxVM in a cluster, ensure
that some space is available on the disk for these logs. The log size is proportional to the
volume size and the number of nodes. For information on DRL, see the Veritas Volume
Manager 5.0.1 Administrator’s Guide and the Veritas Storage Foundation Cross-Platform Data
Sharing 5.0.1 Administrator’s Guide available at:
http://www.docs.hp.com
4. Install the license that supports the clustering feature on every node in the cluster.
